Original Post

We are happy (and quite relieved) to now share our
VirtualBeat Audio Engine for the Virtual Boy: VBeat.
The full engine including the demo song and instruments are published under BSD 3-clause license.
In short: you can do whatever you want with it (just give credits).
However, we welcome feedback and possible contribution by others in the long run.
There is an extensive list of features on the source repository page:
VBeat release.
You will also find some docs and HowTo there.
A YouTube video featuring the tune as well as the player engine is here:

And a recording from real hardware (in fact quite close to mednafen):

You require the ISAS32.EXE assembler and ISLK32.exe linker to build the engine (as well as some .ISX to .VB converter).
The available SDK packages for GBC etc contain these still!

We hope to attract composers with this release and to motivate awesome music in future releases.
The attached ROM is 16KB in size and contains the full tune + some demo tracks (press ‘B’ to toggle tune and demo) + charset and texts as well as the engine and visual output routines. It takes less than 2% of the available time per frame.
We chose to support the very wide spread s3m format as it has all the features we needed and the s3m of the example Jazz tune is part of the release.
We suggest the free multi-plattform tracker ‘Schismtracker’ for composing. A lot of thinking went into a proper data format (see github readme for a full description).

Attachment fails currently but a zipped rom binary is here:

code & design: enthusi
tune & instruments: jammer

This was great fun!
